CARBU RETOR.

SPECIPIGAI'IOI. forming part of Letters Patent No.

356,950, dated February 1.1887.

application filed March 13, 1886. Serial X0. 195,114. (Noinndctl To allwhom it may concern.-

Be it known that l, LYMAN F. MONETT, a citizen of the United States ofAmerica, residing at New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements inCarburetors, of which the following is a specification, ref erence beinghad therein to the accompanying drawings.

This invention pertains to improvements in air-gas carburetors, havingfor its object to provide a maximum amount of carburetingsurface in aminimum amount of space without chilling or refrigerating the gas; toauto matically maintain the hydrocarbon liquid at the required oruniform level or height; to reduce the temperature of the said liquidand to warm the vapor arising from the latter, and to maintain a steadyflow of gas and to facilitate the process of carbureting the same; andthe invention consists of the combinations of parts, including theirconstruction, substantially as hereinafter set forth, and pointed out inthe claim.

In the accompanying drawings, Figure 1 is alongitudinal sectionalelevation of my invention, and Fig. 2 is a cross-section of thecarburetor proper.

In the imbodiment of my invention I suita bly support upon frame-workthe carburetor proper, A, and blower 13, preferably disposing one abovethe other, the carburetor being the lower. The carburetor proper, A,comprises the outer imperforate cylinder or casing, A, and the innerwire-woven or perforated cylinder, A which is adapted to revolve in theformer, as hereinafter described.

The inner cylinder, A, has applied to its inner circumference, whollycovering it, save at small intervals between them, absorbents O, whichare approximatelysemi-cylindric in cross-section, having theirconvexities presented toward the inner or central space of the cylinder.These absorbents G are also made of woven wire or cloth,and filled withasbestos, c0tton-waste,or other porous absorbent. The absorbents, byreason of their aforesaid construction and disposition, provide amaximum amountof gas-carbureting surface in a minimum amount ofspace.The cylinder A is also covered with wick cloth or other porousabsorbent.

Upon the outer cylinder or case, A, is secured a jacket, E,fordistributing warm water upon the said cylinder for warming the vaporfrom the hydrocarbon. The W2IYH1-W3t61 supply pipe is connected to thejacket E at a, while the same after use is discharged at b. The warmingof the hydrocarbon vapor prevents the refrigeration or chilling of thegas. The ends of the cylinder A are provided with convexed heads (1,their convexities being presented outward.

The inner cylinder, A is provided with a central apertured tube or pipe,F, and hung in position within the cylinder A at one end upon a spindleor shaft, 6, bearing in the cylinder or case A, upon which shaft 6 ismounted or secured a sprocket or toothed wheel, the purpose of whichwill appear farther on. The other end of the cylinder A is hung upon theinward horizonta-lly-extended portion of the blast or blower pipe f,passed through that head of the cylinder, and entering at its inner endthe pipe F.

The blower B has upon its inside a fan, B, which takes the air thereintothrough the air-inletg in the upper side of the casing,

while the air is delivered or forced therefrom into the pipe j. whichconducts it into the aperturcd pipe F of the carburetor-cylinder A! I isan endless-chain belt, which is passed around a sprocket or toothedwheel or pulley, h, upon the fan or blower shaft h and around the wheela of the inner carburetor-cylinder shaft "for rotating the said cylinderto effect the constant lifting or presentation of different portions orparticle after particle of the liquid hydrocarbon to the air or blastfrom the pipe F. It is obvious that this operation will preserve asteady flow of gas and facilitate the process of carbureting the same,the latter leaving the carburetor through the outlet i in the upper sideof the cylinder A and being conducted through pipes to the burners foruse. This outlet may have a valve or cut-ofi', if desired, to confinethe gas to the carburetor.

J is a pipe which, in practice, leads to the reservoir or tankcontaining the liquid hydrocarbon, which tank or reservoir is so locatedor arranged that its bottom stands about in the same plane with thelevel or height of that liquidin the carburetor.

H is an automatic overflow-valve, whichis pivoted in a pipe or inlet,is, which latter is disposed in a plane that coincides with the heightor level at which the liquid hydro. carbon stands in the carburetor. Thevalve H will therefore, when the liquid has reached the required levelor height in the carburetor, close; but the moment theliquid sinks orfalls below that point it is obvious that the valve will be opened bythe action of the liquid from without pressing upon it, and thusautomatic cally effect the feeding of the liquid or hydrocarbon to andthe cutting off of the same from the carburetor, and thereforemaintaining the liquid in the carburetor at the required uniform height.

I am aware that it is not new to provide a revolving carburetor withinternal perforated wings or vaneawhereby portions of the liquidhydrocarbon are taken up and delivered in shower or spray to the passingcurrent of air, and an interior grating, the surface of which is coveredwith a thin absorbent coating;'also,

v a carburetor comprising a tank wherein two foraminated cylinders aresecured on a perfo rated pipe or hollow shaft, said cylinders havingcotton-batting inserted between the same; and I am further aware that itis not new to secure within a cylindric vaporizing chamber or generatora perforated shaft, on which are secured two similar disks or metallicplates perforated with numerous holes to receive and support wiclnng orother suitable fibrous rope or absorbent material for vaporizing benzoleor other volatile hydrocarbon, mixing it with air. Carburetors havingwater-jackets on, their ulterior surface; having been heretofore knownand used, I make no claim to such feature; but my invention is designedas an improvement over the devices above outlined, and to this end. Iemploy, in connection with. an outer cylinder having a water-jacket, aninner perforated cylinder covered with Wicking-cloth and absorbentsparallel with the axis of said inner cylinder, and my invention alsocomprises an automatic valve, all of which 9 features have beenhereinbefore described;

By placing the absorbents parallel with the axis of the inner cylinder,as stated, I not only provide the best and most practicable manner ofconstructing the carburetor, but obtain a maximum amount ofgas-carbureting surface in a minimum amount of space, which is adesideratum in this class of inventions;'

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is'- The combination,in a carburetor, with theinner perforated cylinder covered with wickingcloth and the outercylinder having the Waterjacket, of the absorbents, the pipe having theautomatic valve, the blower, and the chainbelt passed around thesprocket-wheelson the shafts of the blower and the inner cylinder of thecarburetor, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
